Additionally, youth internationals Nigel Boogaard, Mark Bridge and David Williams played under Postecoglou while with the Under-17 and Under-20 national teams, ensuring that many of the All Stars already have some idea as to how they'll line up against Manchester United.

"With his experience, being able to gel the boys in a short period of time is obviously key," said Adelaide United defender Boogaard.

"He's done it in the past with national teams, he's experience at being able to bring a group of boys in and only work for a week and get the best out of them obviously is key to us succeeding on Saturday night.

"It'll be the biggest crowd I've ever played in front of, definitely a lot more than the 35,000 odd for the Hyundai A-League Grand Final.

"Obviously I'm excited for the challenge and it should be a big day, probably one of the biggest highlights of my career so far."

The Foxtel A-League All Stars will debut against Manchester United at ANZ Stadium, Sydney, on 20 July with the match to be broadcast live and exclusive on the Seven Network nationally.
